Geologists - scientists who study the forces that make and shape the earth Geology - the study of planet Earth Constructive forces - forces that build up landmasses like mountains Destructive forces - forces that slowly wear away mountains and surface such as what an ocean does Continents - seven large landmasses on earth Seismic waves - waves that move through the Earth's interior Pressure - force pushing on a surface or area Crust - layer of rock that makes up the Earth's outer skin Basalt - dark, dense rock that forms the oceanic crust Granite - rock with larger crystals that is less dense than basalt and makes up the continental crust Mantle - layer of hot rock below the crust Lithosphere - means "stone" and is the mantle and crust together Asthenosphere - means "weak" soft rock material that can flow slowly Outer core - layer of molten metal that surrounds the inner core Inner core - dense ball of solid metal

Geologists - scientists who study the forces that make and shape the earth
Geology - the study of planet Earth
Constructive forces - forces that build up landmasses like mountains
Destructive forces - forces that slowly wear away mountains and surface such as what an ocean does
Continents - seven large landmasses on earth
Seismic waves - waves that move through the Earth's interior
Pressure - force pushing on a surface or area
Crust - layer of rock that makes up the Earth's outer skin
Basalt - dark, dense rock that forms the oceanic crust
Granite - rock with larger crystals that is less dense than basalt and makes up the continental crust
Mantle - layer of hot rock below the crust
Lithosphere - means "stone" and is the mantle and crust together
Asthenosphere - means "weak" soft rock material that can flow slowly
Outer core - layer of molten metal that surrounds the inner core
Inner core - dense ball of solid metal
